White radish, through digging heart measures, can inhibit its early entry into the reproductive growth stage, prolong its vegetative growth period, so that the supply of nutrients at the growing point is converted to promote the enlargement of the fleshy root, and the yield is greatly increased. According to the experiment, digging away the growing point than the white radish that has not been excavated, the yield per mu can be increased by about 2000 kg. The specific approach is: 40 to 50 days before the normal harvest of white radish, that is, when the white radish grows to 0.25 to 0.5 kilograms, select the sunny day, with a small knife, the tip of the knife is inserted into the center of the radish leaves, the growth point dug out, If the dug-out of the heart does not spread to prove that it has dug to the growing point. 5 to 7 days after digging, after the wounds heal, 2000 to 2500 kg of manure water per mu, and 50 to 100 g of urea per 50 kg of fecal water. Be careful to apply it on the side of the radish, do not pour the dung on the radish, so as not to infect the wound with bacteria. Every 10 days after the inspection, if the growing point is still growing, the heart can be dug for the second time. About one month before harvest, when the radish grows to 0.75 to 1 kg, a third inspection is conducted. If the growth point is not dug out or if there are lateral buds, a further digging will be conducted. The main purpose of digging the heart is to make the radish no longer grow new leaves, and can make the radish no longer grow new leaves, and can keep the radish fresh for 3 months. If sold before and after the Spring Festival, the price is high, but can adjust the market surplus. China Agricultural Network Editor
